I just recieved my New Style 200mw Focusable Laser from o-like and it is hard to turn and gets stuck at times. I unscrewed it and it has what seems like wet sticky glue. Why is it like this? Thanks
I think this stuff is meant to keep the focusing head from being too wobbly or to be able to unfocus itself so easy like the first dilda. This one has a firmer focusing grip because of the sticky grease.
Mine had the grease also.
Just levee it their, it wont harm anything.
I made the mistake of wiping it of, because I wanted to use teflon tape instead. Never was able to get to turn as nice as it did, with the grease.
It's used in many optics applications, where there is a focusable element, for avoid that vibrations and occasional touchs may vary the position of the lens holder, changing the focus.
You can freely take it away, but more you take it away, more the focusing assembly may become "wobbling" and unstable.
